Brother Lawrence Gordon, 31, was assistant principal at Mount St. Michael Academy in the Bronx. On Valentine’s Day this year he accidentally left a USB stick in one of the the school’s library computers, which was later found by another teacher. The device contained sexually explicit images of young boys. Gordon was fired.

Authorities knew about the problem in March but Gordon had health problems and had to spend some time in hospital, delaying the prosecution. To avoid going to jail, Gordon pleaded guilty and will spend from a year to a year and a half at a Maryland treatment center. He will also have to sign up on the national Sex Offender Registry.
